Business Insider convened 15 HR and C-suite leaders in Davos to discuss how AI is reshaping hiring and talent pipelines. The roundtable, presented by Indeed, revealed growing concerns about entry-level positions and skills assessment. Deloitte's Elizabeth Faber emphasised maintaining a "human-led, technology-powered" approach whilst carefully navigating reduced junior hiring. TCW's Melissa Stolfi noted her firm has downsized its analyst class but maintains a pyramid structure to preserve apprenticeship culture and future leadership pipelines. Indeed's chief economist Svenja Gudell warned that whilst tech employers now demand five-plus years' experience, this creates future talent shortages if junior hiring continues declining. Salesforce's Nathalie Scardino said her company receives two million applications annually and has shifted focus from years of experience to learning aptitude. Manpower Group's Becky Frankiewicz noted AI can process candidates faster whilst reducing bias, potentially unlocking opportunities beyond traditional qualifications.
Deloitte plans to hire 50,000 employees in India and is evaluating Mangaluru, Karnataka, as a potential new location, according to South Asia CEO Romal Shetty.

The CEO called for streamlining GCC setup processes from six months to two weeks, whilst acknowledging infrastructure constraints around energy and water for data centres. Shetty noted Mangaluru offers advantages including talent availability and real estate, adding the company's presence there is a matter of timing.
